   Apparently, the black and colour cartridges used simultaneously
   in the Deskjet 550C and 560C have incompatible chemical makeups,
   and they should not be mixed at a given print point.

   On the other hand, the newer ones used in the DJ600 series can
   be mixed with no ill effects.

   How would you set the dither knobs to differentiate between
   these two cases. I think it has to do with "set_black_upper()",
   and what is the default action.

The way to handle that is to not pass a black bit vector (pass a NULL)
if you don't want black ink.  I haven't tested this in a while, but
that's how it's supposed to work.
